The LifeStraw Flex Filter is compatible with the LifeStraw Gravity Bag. This versatile filter can also be used as a personal straw filter, connected as an in-line filter to most hydration reservoirs or attached to some disposable water bottles.
This filter contains a membrane microfilter and a activated carbon-ion exchange filter. It protects against bacteria, parasites, and microplastics, lead and heavy metals, chlorine, organic chemical matter like pesticides, herbicides, as well as dirt, sand, cloudiness and odour. This improves the taste of the water.
- Membrane microfilter lasts up to 2,000 L, pore size: 0.2 micron
- Activated carbon + ion exchange filter lasts up to 100 L (replacement capsules are available)
